Combine like terms. x^2y-3xy^2-6x^2y
balu736 [363]

The result after combining like terms is: -5x^2y-3xy^2

Step-by-step explanation:

Given expression is:

x^2y-3xy^2-6x^2y

The like terms are those terms with whom the variable or product of variables is same.

As in the given expression, first and third, both terms have x^2y so both terms are like terms

Combining like terms, means the indicated operation is performed on them

So,

Combining like terms:

x^2y-6x^2y-3xy^2\\= -5x^2y-3xy^2

Hence,

The result after combining like terms is: -5x^2y-3xy^2
